  1. I just went and read some of the instructions for your LOC. Turns out it isn’t a LOC at all really. Your headunit doesn’t have an output at all really. All it does is send a message to the amp and tells it what to do. That’s where the PAC AmpPRO intercepts the message and turn it into audio. There is no conversion from high to low level. Still doesn’t explain why you didn’t get a signal but very much explains why you can turn the head unit up to max with no distortion. 
     

    And then your amp...lots of settings in side that thing.

     

    Start playing around in the amp’s settings (with no speakers hooked up) until you get a signal on the DD-1 to see what is going on. You have so many controls on the amp I’m guess one of those is the issue. It doesn’t appear the the PAC device has any output adjustments except to shut off the factory EQ.

  2. You can check everything with the probes of the DD-1 plugged into the amp outputs. Zero reason to check everything at each point.

     

    • Set the amp and LOC gain all the way down
    • Then check max clean output of the headunit at the amp with the 0db track (which very well could be max).
    • Then with the headunit at that volume setting and using the 0db track turn the LOC gain up until you get distortion.
    • Then do the amp using a -5 or -10db track.

     

    Done. Super simple, don't make it more difficult than you need too. 

  3. no shit you can do it like that. he said he did that. He was confused why that way showed no distortion all the way up at 62 but at the amp it showed distortion sooner at 49. So I suggested the other way to check the head units distortion that is also mentioned in the DD-1 instructions. What's important is what is coming out of the amp. If it says it's distorting at 49 then that is the level you use. 

  4. If it was me in this case, I would check everything at the speaker outputs of the amp. Use the 0db test tones to test everything in line prior to the amp, then use the either the -5,-10, or -15 tracks (probably the -5 or -10) to set the output of the amp. Just make sure the gain is as low as possible when checking everything upsteam of the amp. Making sure the headunit output is as clean as possible is possibly the most important thing. 

  5. Klipsch is nice stuff, can’t stand their subs personally though! But those 820s are the shit. Can’t say I have ever heard audio control home stuff but I’d be shocked if they were less than amazing. That’s going to be intense when it’s done, a lot of speakers in a tiny space!

  6. there were 3 for me really.

    The first was a friends late 80s Monte Carlo or something similar. It had 2 15" punch subs and a punch 500 if I remember correctly (it has been about 25 years ago). This was the first time I heard a system that was well put together.

    The two that hooked me for life were

    1. A local guy's chevy astro van with eighteen 15" JL W6 (the first versions) running on 6 us amps VLX-400s.

    2. His friend that was running a Phoenix Gold MS2250 on 4 Kicker Comp 18s.

    i guess i like the familiar

    last night was Corona, but I wanted something light to drink. 

    It's like picking what I eat for me, I can't eat the same thing every time I eat. I really only drink beer, so I keep a few that are my favorites around and pseudo randomly pick one or two six packs of something I have never had (or at least don't remember). I have found lots of beers I like that way that I probably wouldn't have tried otherwise.
